Intended Use (including indications for use)

The IW900 series Infant Warmers are designed to provide warmth to infants in the first few
weeks of life, when an infant's self-thermoregulation capacity may be reduced, or if external
thermal support is required or desirable. This may include neonates (including premature/low
birth-weight neonates) in Labor and Delivery (L&D) Room applications, thermal support of
premature/low birth-weight neonates and critically ill infants in neonatal intensive care units
(NICUs) and thermal support of infants/pediatrics less than 10kg in hospital nurseries. Situations
which necessitate unobstructed access to an infant or neonate, including during resuscitation or
surgical procedures, may indicate the need for a radiant heat source instead of equivalent
support devices such as infant incubators. The IW900 series warmers may therefore also be
used in the Operating Room.

The IW930/IW950 series Infant warmers are additionally intended to be used for intra-hospital
transport between the above stated specialist treatment areas.

The IW900 series infant warmer is not designed or intended to be used outside of the hospital
environment. The IW900 series infant warmer is not designed or intended to be used in
ambulatory vehicles.

CAUTION

Only competent individuals trained in the repair of this equipment should attempt to service it as
detailed in this manual.

Detailed information for more extensive repairs is included in the service manual solely for the
convenience of users having proper knowledge, tools and test equipment, and for service
representatives trained by Fisher & Pakyel Healthcare.

Fisher & Paykel Healthcare has a policy of continued product improvement and reserves the
right to alter specifications without notice.

This Service Manual is valid for warmers manufactured before June 2008. For Infant Warmers &
accessories manufactured after this date refer to 185045312 Rev A.

Warranty

Subject to any agreement to the contrary, the product described in this manual is warranted
against defects in materials and workmanship for one year from the date of shipment. However,
the warranty is void if the product is damaged as a result of mishandling, accident or misuse. In
no event shall the manufacturer be liable for incidental or consequential damages (e.g. loss of
use) resulting from breach of warranty. All other expressed and implied warranties under law
are excluded to the extent that it can be lawfully excluded.

PART 2: Operation and General Information

2.1 Product Overview

INTRODUCTION The Fisher & Paykel range of radiant warmers are specifically designed

to provide a controlled source of warmth to Neonates.

MODELS The IW910 Baby Control and IW920 Manual Control Mobile Infant

Warmers provide truly mobile and height adjustable warming wherever
needed.

The IW930 Series Baby Control and IW950 Series Manual Control

CosyCot™ Infant Warmers combines an integrated bassinet with four
base accessory options:

IW931 Standard Size Bassinet & Mattress – Preset Base
IW932 Standard Size Bassinet & Mattress – Electric Elevator Base
IW933 Long Bassinet & Mattress – Preset Base
IW934 Long Bassinet & Mattress – Electric Elevator Base

IW951 Standard Size Bassinet & Mattress – Preset Base
IW952 Standard Size Bassinet & Mattress – Electric Elevator Base
IW953 Long Bassinet & Mattress – Preset Base
IW954 Long Bassinet & Mattress – Electric Elevator Base

To these base models optional accessories can be added to suit you

own particular warming needs

The IW960 Baby Control and IW970 Manual Control Wall Mount

CosyCot™ Infant Warmers combine the integrated CosyCot™ bassinet
with the benefits of wall mounting.

The IW980 Baby Control and IW990 Manual Control Wall Mount Infant

Warmers provide discrete and convenient space saving warming.

HEAT CONTROL In Baby Mode (IW910, IW93x, IW960 & IW980 only), the infant warmers

provide stable control of the baby's skin temperature by automatically
adjusting the heater power to compensate for varying physiological and
environmental conditions. This is achieved using a microprocessor which
measures and updates the baby’s temperature ten times every second.

In Manual Mode, all infant warmers provide user-adjustable heater power

and the option to monitor the baby’s skin temperature using the
DuoSense™ skin sensor.

In Prewarm Mode all models provide alarm and trouble-free pre-warming

of the heater.

DUOSENSE™ SKIN SENSOR Safety is further enhanced by DuoSense™ skin sensor. This sensor

measures the desired skin temperature using two independent sensors.
These sensors are continuously compared to ensure accurate and
reliable skin temperature measurements.

OPERATING MANUAL This technical manual is intended to be used in conjunction with the 900

Series Operating Manual (see part numbers below) and Installation and
Assembly Instruction Sheets. The operating manuals must be read
thoroughly and all instructions, warnings, cautions and notes thoroughly
understood by all personnel working with warmers prior to use.

RESOLUTION AND DUTY CYCLE Power to the element is controlled with a triac and switched only on

mains zero crossings to maximise electromagnetic compatibility.

When in Baby Mode, the power is controlled to a resolution of 1%.

Power is delivered in an optimally smooth pattern of mains pulses
which repeats every 2 seconds at 50 Hz (1.7 seconds at 60 Hz). This
even power control helps to reduce ripple in the baby or patients skin
temperature. The power level is automatically adjusted ten times every
second.

2.4 Alarms

2.4.1 IW910, IW93x, IW960 and IW980 Servo Control Models

CHECK BABY ALARM In Baby Mode this alarm means the output power has been at 100% for

at least 15 minutes indicating that the baby is slow rising to the set
temperature and should be checked. In Manual Mode this alarm
means the output power has been above 25% for at least 15 minutes
indicating that the baby should be checked.

HIGH SKIN TEMP. ALARM In Baby Mode this alarm means the baby skin temperature exceeds the

set temperature by at least 1.0°C. In Prewarm Mode or Manual Mode
this alarm means the baby skin temperature exceeds 39°C.

LOW SKIN TEMP. ALARM In Baby Mode this alarm means the set temperature exceeds the baby

skin temperature by at least 1.0°C. This alarm is not active in Prewarm
Mode and Manual Mode. This alarm is disabled for 15 minutes each
time baby mode is started and re-enabled each time the skin
temperature gets within 0.5°C of set temperature.

SENSOR DISCONNECT ALARM In Baby Mode this alarm means a problem has been detected with the

skin temperature sensor. This may mean: (a) If '---' is flashing on the
Baby Skin Temperature Display the sensor plug is not inserted fully into
the socket, and/or (b) that one of the thermistor beads within the
DuoSense™ skin sensor does not agree with the other so that the
sensor can no longer be considered accurate. A bead mismatch alarm
occurs within 25 seconds of the sensor being plugged in. Both
meanings apply in Baby Mode, meaning (b) only applies in Manual
Mode and neither apply in Prewarm Mode.

2.4.2 IW920, IW95x, IW970 and IW990 Manual Control Models

CHECK BABY ALARM This alarm has three meanings:

(a) Manual Mode 15 Minutes
The infant warmer has been running in Manual Mode at over 25%

power for more than 15 minutes. The baby should be checked.

(b) Skin Temperature > 39°C
This alarm is accompanied by a flashing Baby Skin Temperature

Display (which is > 39°C). The baby should be checked.

(c) Skin Sensor Faulty
The DuoSense™ skin sensor feature of the infant warmer has detected

a fault with the skin sensor. This alarm is accompanied by a flashing
Baby Skin Temperature Display. Ensure that the skin sensor is fully
plugged in. If skin sensor is faulty then discard it.

2.4.3 All Models

SEE MANUAL ALARM If the LED is flashing then the software has detected a hazard, has shut

down the heater and entered this alarm state. If the warmer is able to
power up again an error code corresponding to the meaning of the
alarm can be obtained with use of the Information Mode (the error code
is preserved in non-volatile memory).

If the LED is on constantly and is accompanied by a rapidly pulsing two-

tone alarm then the hardware watchdog circuit has detected a micro­controller failure.

If the LED is on constantly and is accompanied by a constant tone then

the overheat protector in the heater has tripped.

POWER FAIL ALARM When this alarm is flashing the power to the warmer has failed.

NOTE: that this may mean the power switch (located on the front panel)

is on while the power at the supply wall outlet is switched off.

No error has occurred.
Temperature multiplexer is not responding

correctly. Temperature cannot be measured.
The two thermistor beads in the DuoSense™

skin sensor are detected to have shorted
together. The skin sensor should be checked.
Using Figure 10.1.2, check that contact A is not
shorted to contact B. If the skin sensor is
operating correctly, then there may be a short
circuit within the unit itself.

The microprocessor stack has overflowed
indicating microprocessor or memory failure.

Button multiplexer is not responding correctly.
Buttons cannot be sensed.

Bad Frequency (the device could not sense the
frequency of the mains power supply at power
up).

One of the regular series of ADC conversions
failed to complete in the normal time. This
suggests that the internal hardware on the
microcontroller has failed and the temperature
readings along with other readings can no
longer be relied on.

Bad LED Toggle (the display driver, U1, which
drives the LEDs and displays and scans the
buttons was detected to be faulty).

Serial Buffer Overflow (the RS232 output serial
communications buffer was detected to have
overflowed).

Missing Triac Firing (the triac which controls
power to the element was sensed as delivering
insufficient/uncontrolled power to the element).

NOTE: This error may mean the one of the
backup hardware circuits has independently
detected a fault and disconnected power from
the element.

Spurious Triac Firing (the triac which controls
power to the element was sensed as delivering
additional/uncontrolled power to the element).

Relay Out (the relay which isolates the element
in the event of continuous full power to the
element or hardware watchdog failure is
detected to have opened).

Actions to be taken

correctly. If the skin
sensor is operating
correctly, contact

DEVICE UNTESTED

Non-volatile memory error (a problem was
detected with the non-volatile memory - most
of these errors can be recovered from by
switching the device off then on again).

A device configuration is not selected. The
device is configured during manufacture and
cannot run if a particular model variant has not
been set.

One of the buttons is stuck down. This can be
caused by holding one of the buttons down
while the device is turned on.

The light has been detected as turned on
when it should be turned off. There is either a
fault in the light control circuitry or the light
sense circuitry.

Measurement from the temperature
references are so far out of tolerance that
auto-calibration of the skin sensor

land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
an IW900 series warmer is used exceeds the applicable RF compliance level above, the IW900 series
warmer should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocation the IW900 series warmer.

3.6.5 Base Level Adjustment (IW93x and IW95x models only)

NOTE: Required on warmers with electric elevator bases and preset bases manufactured pre­February 2004. After this date a new preset system means that base level adjustment is not required.

If the base or column are not level, then adjustment of the straight tie rod is required. The straight tie
rod is located underneath the base between the centre pivot and the rear legs.

a. Undo the lock nut that secures the straight tie rod to the ball joints.
b. In the middle of the rod is a flat section that should be used for adjustment. Use the 6 mm
wrench (part of the tool kit) to turn the rod. One full clockwise turn of the rod (thread M8 x 1.25) will
lower the column down by approximately 4 mm. Hence, one full anti-clockwise turn of the rod will lift
the column end up by approximately 4 mm.
c. Adjust to level column and base.
d. Tighten the lock nut.

NOTE: When the rod is assembled, the ball joints remaining threaded portions are:
Leg side: 10 mm (full length is 20 mm)
Pivot side: 10 mm (full length is 25 mm)

CAUTION

A maximum of four full clockwise turns are allowed (remaining threaded portion 5 mm).

3.6.6 Castor Angle Adjustment (IW93x & IW95x models only

If the castor is not vertical to the floor, adjustment of the link arms is required. The link arms are
located underneath the leg. Castor angle cannot be adjusted on warmers after the above serial
number – refer to PART 12: for serial number identification.

Undo the lock nuts that secure the straight tie rod to the ball joints.

a.
b. In the middle of the arm are two holes spaced at 90°. Use a 3mm Allen key or a 3mm bar to

turn the arm. One full clockwise turn of the arm (thread M10 x 1.5) will move the castor
outwards by approximately 3 mm. Hence, one full anti clockwise turn of the arm will move the

castor inwards by approximately 3 mm.
c. Adjust the castor to the vertical position.
d. Tighten the lock nuts.

NOTE: When the arm is assembled the remaining threaded portions on both sides are 13 mm
(including 8mm thick lock nuts).

CAUTION

A maximum of ten full turns clockwise are allowed (thus the remaining threaded portion

will be 10 mm).

3.6.7 Bassinet Clutch Adjustment (IW93x, IW95x, IW960 & IW970 models only)

If the bassinet can be tilted without actuating the rear handle, or pulling the two handles together
doesn't allow tilting of the bassinet, then the bassinet tilt clutch requires adjustment.

Adjustment is performed with the adjuster screw (for fine alterations) or by moving the cable support
block (for coarse alterations).

If Bassinet Clutch is too tight (i.e. bassinet can not be tilted):

a. Loosen lock nut on adjuster screw and wind screw out. If screw is already fully wound out then

cable support block will have to be moved.
b. Use a 4mm ball ended Allen key to loosen the two grub screws securing the cable support

block to the bassinet frame.

NOTE: On version three bassinets (manufactured from November 2002) a single M8 cap screw has

replaced the two grub screws, a 5mm Allen key is required to loosen this screw.

c. Wind the adjuster screw approximately half way out.
d. Butt the adjuster screw against the cable sheath by sliding the cable support block towards the

rear of the warmer.
e. Fix the cable support block in position by tightening the two grub screws.
f. Move the bassinet tilt brake handle backwards as far as it will go and wind adjuster screw out to

take up tension.
g. Tighten adjuster screw lock nut.
h. Pull the bassinet rear handle forwards and check brake release operation.

If Bassinet Clutch is too loose (i.e. bassinet can be tilted without using the bassinet handles):

a. Loosen lock nut on adjuster screw and wind screw in. If screw is already fully wound in then

cable support block will have to be moved.
b. Use a 4mm ball ended Allen key to loosen the two grub screws securing the cable support

block to the bassinet frame.

NOTE: On version three bassinets (manufactured from November 2002) a single M8 cap screw has

replaced the two grub screws, a 5mm Allen key is required to loosen this screw.

c. Wind the adjuster screw approximately half way in.
d. Follow steps d to h above.

If the clutch is still loose the actuator spring can be tightened. Referring to diagram in section 7.12;
using a ball ended 4mm Allen key on the M5 screw (part 15) and a 6mm open spanner on the
actuator (part 12) tighten the spring by winding the screw in. The 12mm washer (part 16) should
coincide with a line on the lower tilt link molding (part 7). Cleaning the tilt brake sliders (part 10) with
alcohol to remove any particles can also improve the clutch performance.

3.6.8 Bassinet Brake Adjustment (For CosyCot
system)

If the bassinet can be tilted without actuating the rear handle, or pulling the two handles together
doesn't allow tilting of the bassinet, then the bassinet brake requires adjustment.

Adjustment is performed with the adjuster screw on the cable:

a. Move the bassinet so that the handle is in the lowest position
b. Loosen the lock nut on the adjuster screw.
c. Wind the screw such that there is 2mm of play in the lower handle (winding it out will reduce the

play).

d. Tighten the adjuster screw lock nut.

IW900 Series Controller Overview

The controller electronics are mounted behind the front control panel on two printed circuit boards (PCBs)

-

the Control PCB and the Power PCB (see section 5.4 for PCB component photos):

POWER PCB The power PCB provides power supply and I/O lines necessary for

sense and control of the examination light and heating element. It holds
the mains voltage parts and incorporates a heat sink. The power PCB
is connected to the control PCB by a single 14-way ribbon cable (J3).
Also connected to the Power PCB are the power transformer (J10 and
J9), the heater, light and thermal cut-out harness (J7 and J8), the power
switch (J13 and J6) and the mains input terminals (J5).

CONTROL PCB The control PCB is based around the Phillip’s 80C552 micro-controller.

It provides a user interface, temperature measurement and intelligent
control of the element power. Almost all of the warmer functions are
implemented in software. The control PCB is connected to the Power
PCB (J1), the skin sensor socket (J2) and the serial communications
port (J12).

5.3 Circuit Description

5.3.1 Software Independent Safety Circuits

Five safety features are included which function independently of the micro-controller. These safety
features are provided in addition to the safety features already provided by the micro-controller software.

OVER TEMPERATURE COMPARATOR A comparator (U12B) is used to disable heat in the element if a skin

temperature exceeding 39.5°C is detected (see Performance Check
Procedure in Section 3.3). Under normal conditions the software will
not allow this to happen because a
will exist and the power will be reduced to 0%. If a fault prevents the
software alarm from occurring then this comparator will stop the micro­controller from applying power to the heater element. The micro­controller will then cause a See Manual alarm with error code 17
because it will sense that it can no longer control the heater.

100% OUTPUT MONITOR A counter circuit (U13) is used to detect when uncontrolled mains

voltage is applied to the heating element. It does this by counting how
many continuous mains pulses are supplied to the element. If this
count exceeds a threshold value then relays RL2 and RL3 will open
thereby disconnecting the element from the mains supply. Under
normal conditions the software will not allow this to happen. If this
circuit detects continuous full power in the element and opens the
relays then the software will detect it is unable to control the element
power and will show a See Manual alarm with error code 17.

WATCHDOG & RESET OSCILLATOR An external hardware watchdog is included which monitors activity of

the micro-controller. If the micro-controller is not regularly toggling the
watchdog pin, then a See Manual alarm will be started (see Section

2.4) and the micro-controller will be reset. Power to the element will be
disabled.

high temperature alarm condition

OVERHEAT THERMAL CUT-OUT Thermal cut-out (rated at 150°C) is fitted in the heater which will cause

power to be removed from the element in the event of overheating
(within the heater). If this thermal cut-out is tripped then relays RL2 and
RL3 will open thereby disconnecting the element from the mains supply
and a See Manual alarm will result (see Section 2.4).

POWER FAIL ALARM The energy stored in the super capacitor C22 provides up to 10 minutes

of pulsing alarm in the event that power fails while the unit is switched
on. The alarm sounds self-oscillating buzzer PZ2 and flashes the
power fail LED.

5.3.2 Software Controlled Circuits

The remaining circuit components are used in conjunction with the micro-controller software:

MICRO-CONTROLLER

PROM AND EEPROM

U4 is a Phillip’s 80C552 which controls most aspects of the warmer.

U8 contains the micro-controller software and many non-volatile presets
are contained in U7. U7 can only be serviced by the manufacturer
because it contains factory preset information.

RS232 COMMUNICATIONS U6 provides an RS232 interface with the micro-controller. This is used

for manufacturing purposes only.

BUTTONS & CONTROL KNOB All user input is via the buttons or the control knob. The encoder

SW11 has a two-wire quadrature output that allows the micro-controller
to sense movement and direction. U2 and U3 multiplex the buttons into
a single line that is used as an input by the micro-controller.

DISPLAYS & INDICATORS U1 drives the displays and indicators which are configured in four

banks. A single line from U1 is used as feedback to the micro-controller
(test point TP9).

LIGHT CONTROL & SENSE Relay RL1 controls the examination light and U16 provides feedback on

the state of the light to the micro-controller.

HEATER CONTROL & SENSE Triac Q22 controls the power to the element. It is opto-isolated with

U15. Relays RL2 and RL3 allow the

WATCHDOG circuit to remove power from the element if a fault is

100% MONITOR circuit and the

detected. Current pulses in the element are sensed via coil T1 (test
point TP15).

PITCH & VOLUME CONTROL BUZZER U19 provides pitch and volume control over buzzer PZ1 which plays all

alarm and acknowledge sounds.

ZERO CROSSING & LINE LEVEL SENSE The mains voltage is monitored by a secondary winding from the power

transformer. Comparator U14E detects zero crossings and a waveform
is derived (found at test point TP14) which exhibits a momentary
negative going pulse on each zero crossing. A DC voltage proportional
to line voltage level is detectable at TP8.

PART 6: Head and Column

6.1 Head Assembly

6.1.1 Head Assembly Change History Version 2

From August 2002 changes were made to the upper and lower cases of the head assembly to facilitate
an additional bracket at the rear of the head. This version of head is most easily recognisable by the
extra screw on the bottom face of the head in-between the former hinge.

NOTE: The lower case no longer swings down on a hinge.

A new spares kit was created to allow the replacement of old style upper and lower cases (043042359
– Kit Head Case Replacement) which includes both the upper and lower cases, labels, diffuser glass,
new bracket and Nomex insulation.

Version 1

The original head assembly manufactured from January 1997.

Light Box

The original aluminium light box

(648040141) was replaced with a black injection molded part
(693041858) from October 1998. The two M3 x 16 Taptite screws (614040818) previously used for
retaining the lamp receptacle are not required with the molded part which has snap fits for holding the
receptacle.

In May 2001 the snap fits were altered to fit a new receptacle style. If a replacement light box
(693041858) is required for a warmer prior to this date then a new lamp receptacle (342042009) will
also need to be ordered.

Lamp Receptacle

A new lamp receptacle (342042009) was used from May 2001.

This receptacle can not be retrofitted to
earlier warmers. The original square receptacle (341040500) will not fit into light boxes in warmers
manufactured after May 2001.

Head Manufacture Date

The date of manufacture of the head can be found underneath the head label (3) on the very top of the
head. This manufacture date applies to the head only and should not be used when referring to the
warmer as a whole unit.

Head Nut Removal Spanner

As of June 2003 a bent wire tool (171042012) is available for the removal of the head nut (648040142)
and replaces the plastic tool (171040032) previously included in each warmer.

Swivel Head

From January 2003 the IW910AFS is available. This contains a swivel head for the French Market.

assembly. The reflector is placed in the plastic head molding such that aluminium flat is positioned
under each of the four (two per side) plastic tabs in the upper case. The reflector should sit evenly
in the head under the four front plastic tabs and Nomex.

NOTE: Reflectors manufactured prior to June 2003 were not symmetrical, In this case the end with the

two step cut out goes to the back of the head.

6.4 IW93x/95x CosyCot™ Column Assembly

6.4.1 CosyCot Column Assembly

Variations in the column assemblies are most easily discernible by the number of column extrusions
used and are defined as such.

Version 3 – Two Part Column Assembly

From July 2001 the two upper columns were combined into a single column (642042024) and a foam
gasket (331042014) replaced the upper Mylar gasket. The upper column harness (23) was also
changed to remove the middle column earthing points.

Version 2 – Three Part Column Assembly

From July 1998 the single column was replaced with a three-piece construction consisting of a
substantially thicker lower column (641040737) and two standard sections (641040740 and

641040815). Internal Mylar gaskets were added to create an oxygen compartment for the Neopuff
and gas accessories and the dovetail sliders (641040738) increased to 200mm. The column harness
was broken into two harnesses to ensure each section of column was earthed.

Version 1 – Single Column Assembly

The original column assembly manufactured from January 1997 and consisting of a single powder
coated aluminium extrusion as the backbone of the assembly.

Change History

Column – Base Bolt Variations

The original M8 bolts used up until March 1998 were replaced with a separate stud (614040859) that is
fixed into the lower column and a special M8 x 16 screw (614040858). This change is in conjunction
with a change to the base assembly and the studs will only fit into these bases (with 12.8 mm
mounting holes). For earlier bases a replacement bolt (614040346) is available.

PART 7: CosyCot™ Bassinet

7.1 Bassinet Change History

Version 3.1

This bassinet is centrally mounted off shoulder bolts rather than brackets off the rear. As a result the
extrusion has extra holes and the brake system has been upgraded.

Version 3

This bassinet has lift and fold side panels and an adjustable transport handle. Also included are silicon
tube tidies in the corner caps and on each of the front and rear panels. A modified bassinet extrusion
removes many of the aluminium dovetail blocks for fixing the rear handle, brake cable and x-ray tray.

Version 2.5

This bassinet has lift and fold side panels and an adjustable transport handle. Also included are silicon
tube tidies in the corner caps and on each of the front and rear panels.

Version 2.1

Version 2.1 varies from its predecessor by the inclusion of high profile corner caps and silicon corner

tube tidies. This change necessitated a new set of side panels (043042201/202).

Version 2.0

In version 2.0 the fabric underlay was replaced by an ABS plastic sheet (255040074) and the corner
block caps replaced with an injection molded part. This model also allowed the use of side panels with

sealing strips to ease cleaning and coincided with the introduction of the long bassinet (900IW212).

Version 1

The original standard bassinet is most easily distinguished by the blue fabric underlay (254040068) on
which the mattress was supported.

7.2 Side Panel Change History

The full range of side panels are shown in section 7.9. Included in this section is an identification chart
which can be faxed out to customers to ensure accurate identification of the spare side panels when
they are requested. In all instances the second number in each heading refers to a long side panel.

7.2.1 Side Panel Axle Changes

Bassinets prior to version 2.5

contained two dummy axles (693041414) in each corner cap that

interlocked with two sliding axles (693041415) in each side panel.

DUMMY AXLE

- 693041414

SLIDING AXLE - 693041415

A

B

C

D

694042168/9

Type A and Type B

The interlocking rectangular section used on dummy axle (Type A above) was thickened and rounded
on two sides in June 1997 (Type 2). At the same time the corresponding hole in the sliding axle was
enlarged to accommodate the increased axle section.

Type C

In February 2001 an additional circular spigot was added (Type C) to aid in the alignment of the two
axles when installing a side panel. Again the corresponding hole in the sliding axle was lengthened to
accommodate the increased axle length.

Type D

The move to Lift and Fold Side panels in May 2002 resulted in two new sliding axles with a large
protrusion from each (instead of the holes in Types A - C), and the omission of dummy axles all
together.

Upgrading Side Panel Axles

Either Type A or Type B axles can be upgraded to Type C by simply removing the corner cap from the
bassinet, pulling out each axle and inserting new 693041414 axles.

NOTE: The sliding axles in each side panel will also need to be changed.

All hands free side panels from February 2001 onwards used Type C sliding axles and will fit onto both
Type B and Type C dummy axles. Manufacture of the hands free side panels ceased in November
2002 after which dummy axles were no longer required in the assembly.

Side panels manufactured previous to February 2001 will have Type B sliding axles that will NOT fit on
Type C dummy axles. Follow the steps in section 3.5.11 to replace sliding axles if required
